Fig. 2 shows the controlled primary coil unit 10 according to an execution mode of the application, wherein, for
As shown in Figure 2, controlled primary coil unit 10 comprises a plurality of conductors 101 and a plurality of the first gate-controlled switch 102.In Fig. 2, for purpose clear and signal, only show 9 conductors 101 and 9 the first gate-controlled switches 102.A plurality of conductor 101 is arranged in a crossed manner, and is coupled with first gate-controlled switch 102 between per two positions arranged in a crossed manner.In one embodiment, a plurality of conductors arranged in a crossed manner 101 are arranged at least on the two-tier circuit plate, spatially with certain angle of intersection (for example 90 degree or other angles), but directly contact.A plurality of conductors can comprise the conductor and the conductor that vertically arranges of horizontally set, and the conductor of the conductor of horizontally set and vertically setting is arranged at the different layers of circuit board.For example, the conductor of all horizontally sets is arranged on same layer, and all conductors that vertically arrange are arranged on another layer.And in another embodiment, in order to increase the sectional area of conductor, each conductor can adopt Multi-layer Parallel, and the concrete number of plies can be adjusted according to the rated current of energy emission system.For example, if when each conductor adopts 3 layer circuit boards in parallel, 1-3(or the 1st, 3 then, 5) layer circuit board can be used to arrange horizontal conductor, and 4-6(or the 2nd, 4,6) layer circuit board can be used to arrange longitudinal conductor.In addition, conductor can comprise Copper Foil or be parallel to metallic conductor on the Copper Foil.
The first gate-controlled switch 102 can for example be mechanical switch, for example relay.The first gate-controlled switch 102 can for example be the electronic switch that comprises Mosfet or transistor also.
In this embodiment, thus also can in system 100, arrange and can determine the energy receiving system with respect to the position of coil unit 10 so that controller 20 is selected the device of the switch conduction corresponding with determined position.Fig. 3 shows and can determine that the energy receiving system is with respect to the energy emission system 200 of the position of coil unit 10 according to the circuit resonance principle according to an execution mode of the application.Yet the execution mode that passes through resonance principle work shown in Figure 3 only is the application's a exemplary embodiment, rather than is used for limiting the application.
As shown in Figure 3, system 200 also can comprise coil control and drive circuit 30 and the resonant capacitance 40 of connecting with initial coil unit 10 except comprising the controlled primary coil unit 10 and controller 20 that comprises such as above-mentioned system 100.
In this embodiment, controller 20 is at first determined the energy receiving system with respect to the position of controlled primary coil unit 10, and gate-controlled switch conducting corresponding to position that go out of selecting and confirming.For example, at holding state, controller 20, for example periodically, control the switch conduction of predetermined number in the first gate-controlled switch, thus so that the primary power emitter region (detecting coil loop) of the energy emission system that the conductor that couples with closed the first gate-controlled switch is formed for determining whether that target (energy receiving system) exists.For example control gate-controlled switch K1-K9(shown in Fig. 4 (a)) conducting, thus form initial coil path 103, this path is corresponding to shown in (such as Fig. 4 b) that cover whole controlled primary coil unit) the detecting coil loop.Meanwhile, controller 20 sends 1 very short impulse train and is added in two ends 103a and the 103b of formed coil path 103 by coil control and drive circuit 30, so that coil path 103 and resonant capacitance 40 resonance of connecting are in first frequency.Controller 20 is with the voltage at detection computations coil path 103 two ends subsequently.If there is not target to be present in the first detecting coil loop scope of energy emission system 200, the resonance frequency of coil path 103 just can not change, the voltage at coil two ends just can not change, on the contrary, if when having target to be present in the detecting coil loop scope of energy emission system 200, the resonance frequency of coil path 103 will change, and therefore, the coil voltage that controller 20 detects will decrease.When the voltage that detects when controller 20 was lower than default in advance threshold value, controller 20 was determined target Already in the detecting coil loop scope of energy emission system 200.
In case controller 20 is determined target Already in the detecting coil loop scope of energy emission system 200, it will further determine the position of energy receiving system again by the scanning searching movement of controlled primary coil.In one embodiment, determine the energy receiving system Already in the detecting coil loop scope of described emission system after, controller 20 scans to determine target with respect to the position of described controlled primary coil unit according to following principle to described controlled primary coil unit:
1) in a plurality of gate-controlled switches 101, selects first group of switch conduction, and determine the size of the reflected energy that the coil path (primary coil loop) that forms by first group of switch and the conductor that is coupled thereof receives from described energy receiving system; For example, select the coil path (primary coil loop) of first group of switch conduction formation as being labeled as A among Fig. 5.Simultaneously, under the control of controller 20, apply the impulse train with scheduled duration to the primary coil loop by coil control and drive circuit 40, thereby so that this path works in the second resonance frequency with the resonant capacitance of connecting, so be transferred to regard to having a small amount of energy in the resonant circuit of receiver, after impulse train finished, this energy value that is transferred can reflex in the controlled primary coil of transmitting terminal immediately.The second resonance frequency can be identical with the first above-mentioned resonance frequency or also can be not identical.
2) select second group of switch, and determine the size of the reflected energy that the primary coil loop that forms by second group of switch and the conductor that is coupled thereof receives from described energy receiving system; For example, can select the second group switch conduction adjacent with described first group of switch, perhaps select to have with described first group of switch second group of switch conduction of certain distance.In this embodiment, select second group of switch conduction to form as being labeled as the primary coil loop of B among Fig. 5.
3) the rest may be inferred, according to the direction shown in the arrow among Fig. 5, the gate-controlled switch of the predetermined number in the described controlled primary coil unit scanned; And
The primary coil loop is as the transmission coil to described energy receiving system transmitting energy when 4) selecting reflected energy maximum, and at the Energy Transfer initial stage, can do further scanning to selected transmission coil, to determine target with respect to the exact position of primary coil loop.Should be appreciated that controlled primary coil is the closer to energy receiving system (energy receiving coil), the energy of transferring in the resonant circuit of energy receiving system is more, and therefore, the energy value that reflexes in the controlled primary coil is also higher, otherwise, then lower.Controller 20 scans the size of the energy value of each position back reflection in the controlled primary coil by determining controlled primary coil, determine the approximate location of receiving coil, for example: when controller 20 is determined: when the L position is arrived in controlled primary coil scanning motion, the energy value that reflexes in the controlled primary coil is maximum, and then the corresponding energy in L position emitter region (primary coil loop) is exactly position corresponding to target.
In addition, as shown in Figure 6, also can be coupled with a plurality of the second gate-controlled switches 50 between each gate-controlled switch 101 and control and drive circuit 30, each second gate-controlled switch 50 also is coupled with controller.Detect the existence of target when controller 20 after, will send control signal by port C (K1-Kn), it is closed to control corresponding the first gate-controlled switch, thus the conductor forming energy emitter region (primary coil loop) that will be in described a plurality of conductors be coupled with the switch of conducting.Simultaneously, controller 20 is by port OD1 ~ ODn export target detection control signal, control the second gate-controlled switch conducting corresponding with the first switch of conducting, thereby so that the impulse train that controller 20 sends can be applied to by coil control and drive circuit 30 two ends of formed path.The same with above-mentioned the first gate-controlled switch of mentioning, the second gate-controlled switch can be mechanical switch equally, maybe can be the electronic switch that comprises Mosfet or transistor.
Abovely be described with reference to the exemplary embodiment of accompanying drawing to the application.It should be appreciated by those skilled in the art that above-mentioned embodiment only is the example of lifting for illustrative purposes, rather than be used for limiting.All in the application instruction and the claim protection range under do any modification, be equal to replacement etc., all should be included in the claimed scope of the application.
